Take a deep breathe, Instagram users. Your timeline will now revert back to normal.

Outrage spread throughout social media on Thursday as Instagram users were greeted by a major interface change that completely transformed the way their timeline worked. However, the design overhaul that was widely rolled out is now being rolled back.

Sorry about that, this was supposed to be a very small test but we went broader than we anticipated. 😬

According to Head of Instagram, Adam Mosseri, the big Instagram change was a test accidentally launched to a much wider audience than intended.

The horizontal scrolling timeline change was meant to be shown to only a small test audience.

Users saw this message on their phone screen before viewing the new timeline.

Instagram users that had received the UI update opened the app and found they were now forced to tap left and right to see a new post instead of scrolling up and down through their feed. The new horizontal scrolling timeline also allowed for only a single piece of content to show at a time.

The Facebook-owned social network usually announces major updates with a blog post. This wasn’t the case this time around. Users were also not given a choice to avoid the new interface as an app update wasn’t required to see the timeline change.

Should already be rolled back. If you're still seeing it you can simply restart your app and you should be good to go.
